EDGE IRONING, FOLDING, AND SHAPING MACHINE.

Specification of Letters Patent.

Patented June 29, 1909.

Application filed November 15, 1904. Serial No. 232,804.

To all whom it may concern:

Be it known that 1, PETER 11. Liaison, citizen of the United States, residing at Minneapolis, in the county of Hennepin and State of Minnesota, have invented certain new and useful Improvements in Edge Troning, Folding, and Shaping Machines, and I do hereby declare the following to be a full, clear, and exact description of the invention, such will enable others skilled in the art to which it appertains to make and use the same.

My invention has for its object to provide a simplified and improved device for folding collars and for ironing the folded edges thereof.

To such ends, the invention consists of the novel devices and combinations of devices hereinafter described and dei'ined in the claims.

The invention is illustrated in the accompanying drawings, wherein like characters indicate like parts throughout the several views.

Figure 1 is a vertical section taken through the improved device on the line if of Fig. 2, some parts being left in full. Fig. 2 is a plan view of the said device, some parts being broken away, and some being shown in section. Fig. 3 is a detail, with some parts broken away, taken on the line a a; of Fig. 1 and Fig. 4 is a detail view in bottom plan, showing the ironing shoe or head, some parts being broken away.

The numeral 1 indicates the bed plate of the machine which, as shown, has cast integral therewith a pedestal 2, a vertical bearing sleeve 3, and depending bearings 4. The pedestal 2 is hollow, and the upper end thereof is horizontally extended and terminates at a point approximately over the axis of the vertical bearing sleeve 3. A horizontal countershaft 5 is journaled in the bearings 4, and a vertical spindle 6 is journaled in the bearing sleeve 3. The countershaft 5 has a loose pulley 7 and a fixed pulley 8, as shown, at its intermediate portion, and at its inner end, carries a bevel pinion 9, that meshes with a bevel gear 10 on the lower end of the spindle 6. The spindle 6 carries a feed roller 11. This roller 11 should either be constructed entirely of rubber, or should be provided with a rubber face.

The numeral 12 indicates an ironing shoe or head which is provided with a laterally the front wall of the shoe 12.

projecting stem 13, is formed with a combustion chamber 14 that is open at its top, and on its under surface, said shoe is formed with a groove 15. The stem 13 is inserted into the hollow horizontally extended end portion of the pedestal 2, and pivoted thereto at 16. A coiled spring 17 which, as shown, is seated within a plug screw 18 threaded into the pedestal 2, presses against the stem 13, and yieldingly forcing upward the stem 13% against a stop screw 19 threaded through the top of the said pedestal. The groove in the bottom of the shoe 12 is straight at its forward portion and is curved at its rear portion, as best shown in Fig. 1, in which view, however, the shoe being turned upside down by movement from end to end, shows the said slot with its curve at the forwardly projecting end. The form of this groove is important, as will hereinafter appear. A burner nipple 20 opens into the combustion chamber 141, as shown, through A flexible tube 21 applied to said nipple serves to conduct the gas, or the gas and air, from a suitable source, or sources, of supply (not shown), to the said nipple.

A ridge plate 22, which is set edgewise in a perpendicular position, is iirnily supported by a standard 22% secured on the base plate 1. This ridge plate 22 is straight at its forward portion and is curved at its rear portion, as indicated at 22, part way around the roller 11, but on the arc of a larger circle. The intermediate portion of the upper edge of said ridge plate fits within and follows the groove 15 of the shoe 12, but should be spaced apart therefrom far enough to permit the passage of the collar between said parts. This clearance between the edge of said plate 22 and the said groove 15 may, of course, be varied at will by adjustments of the stop screw 19. The ridge plate 22 passes so close to the adjacent peripheral portion of the roller 11 that said plate will hold the collar firmly pressed against said roller.

To press the other flap of the collar against the outer face of the ridge plate 22, a small presser roll 2 1 is mounted in the free upper end of a spring arm 25, which arm, at its lower end, is, as shown, rigidly secured to the standard 23.

It is, of course, evident that by the combustion of gas within the shoe 12, the said shoe will be kept hot, and that the temperature thereof may be varied by the regulation of the supply of gas, such means for this being well understood and requiring no illustration in this application.

It will be understood that this device is especially adaptedfor use in folding and ironing turn-over collars, and that the collars, before being run through this machine, have first been ironed fiat and have been dampened on the line thereof where the ridge is to be formed by this machine. The flattened dampened collar is placed with the dampened ridge on the upper edge of the ridge plate 22, is bent down over the same, and is started between the ridge plate and the roller 11 on the one side, and the ridge plate and. the presser roll 2-1 on the other side. By the action of the rotating feed roller 11, the folded collar will be fed toward and over the curved end 22 of the ridge plate, and the ridge or bent upper edge of the collar will be forced against the hot walls of the shoe channel or groove 15, and will be thereby ironed. The curved portion of the groove 15, and the curved portion of the ridge plate, curve or coil up the collar as it is fed rearward, and it is here important to note that both the groove 15 and the upper edge of the ridge plate 22 incline downward from their forward. or receiving portions toward their rear or delivery portions, so that in the act of ironing and coiling the collar, its forward end, or that end which is in advanee, will be turned downward in such manner that by the time it reaches the vertical plane of the straight portion of said ridge plate, it will be lowered below the same and clear thereof. In fact, the coiled collar in the machine described may coil. itself entirely around the roller 11, standard and spring arm 25.

The advantage of being able to turn out from the machine a well coiled collar is well understood by all persons familiar with the laundry business. Usually this has been done by hand after the collar has passed from the machine.

The machine described, while extremely simple and of small cost, is efficient for the purposes had in view.

It will be understood that the device described is capable of modification within the scope of my invention as herein set forth and claimed. The machine above described, as 1s ev1- dent, is an edge ironing, folding and shaping machine.

What I claim and desire to secure by Letters Patent of the United States is as follows:

1. A machine of the class set forth, comprising, in combination, a suitable frame, a vertical feed roller, a ridge plate adjacent to said roller, a coiler comprising an upright plate adjoining said ridge plate and curved around and spaced from said roller, an ironing shoe above said ridge plate, means for raising said. shoe above said ridge plate, and means for adjusting the amount of pressure between said shoe and ridge plate.

2. The combination with the plate 1 having the pedestal 2, the upper portion of which is hollow and is extended armroximately parallel to said plate 1, of the power driven feed roller 11 journaled on said plate 1, the ridge plate 22 supported from said bed plate, having the curved end 22 the spring supported press roll 24 on the outer side of said ridge plate, the ironing shoe 12 having the chamber 14., stem 13, and groove 15, said stem projecting into the end of said pedestal 2 and pivoted thereto at 16, and said groove 15 receiving the upper edge of the ridge plate, a spring yieldingly pressing said shoe up ward, a stop screw for variably pressing the same downward, and. means for supplying the combustible fluid to the said chamber 14, substantially as described.

In testimony whereof I my signature in presence of two witnesses.

PETER H. LARSON.
